I have a single exchange server is users are not receiving external Read receipts. The users do receive delivery receipts.<br />
Internal - internal recieve both types.<br />
We do use an hosted spam solution but I have checked the quarantines and this is not blocking them.<br />
The issue seemed to occur when we change ISP. Everything was fully functioning previously. To compensate for this we started using a payed for smtp gateway. Still not getting receiving Read receipts although other customers using this smtp gateway do receive their receipts.<br />
<br />
I hope this explains all and that someone can help<br />
<br />
Kind Regards<br />

Not receiving external Read receipts

Interactions between email servers and clients are governed by email protocols. The three most common email protocols are POP, IMAP and MAPI. Most email software operates under one of these (and many products support more than one).  The correct protocol must be selected, and correctly configured, if you want your email account to work.
